A triple answer, to keep the off-topic post count to a minimum.

It does not happen often, but I gave you a star for that post.
I, as one of those that think that the most probable way of reaching our present situation was evolution, am also one of those that think that similar
conditions would give similar results, in the same way there are Australian marsupials that look like their equivalent mammals on everywhere else.
In that case, I do not find it hard to believe that if there is an evolved species on another planet that evolved in more or less the same conditions
as us on Earth then it is very likely that they look somewhat like us.
But there is also the possibility that they look nothing like us. The only reason we have technology is because of our brains and because we have
hands with which we can do things, but there are species that are equally well equipped to build things, only their brains left them behind, so I
think that it is possible that in a different set of conditions, although similar, a species looking nothing like ourselves could be the most advanced
in a different planet.
Also, the hypothetical superiority is relative, was an hypotetical European superiority the reason for us to reach Japan and not the other way around?
It wasn't, it was the economical situation of both civilisations that made one reach for the other.

I don't know if life is the rule everywhere, but it sure is here on Earth.
And I agree with you, the way things "fit together" must be the same everywhere, but only if the conditions are the same, that is why you can not
use glue in very cold weather, it only works that way if some conditions are present.

Other animals also have two legs, it's just the name we give them that makes the difference.
The fact that we take much more time than other animals to walk is not just because we walk on two legs, if that was the case we could walk on four
soon after being born, right?
That difference is, I think, because we are born without achieving the same kind of preparedness that other species have, so we have to complete the
process outside the womb. Some species of sharks, for example, born from eggs inside their mothers womb, and they fight each other before being born,
so only one is born from each "pregnancy", but it is the fittest of all.
We probably have to born sooner because we are very large when we are born (not all, I was born only with 2.2 kg, but that was because I was born one
month before my time), and if we were to stay more time inside the womb that would lead to more difficult births.
Also, intelligence is not directly connected with the number of legs, if that was the case then kangaroos should be more intelligent than they are.
The case is more clear with birds, where there are great differences in intelligence, although all have two legs.
